Hi,
I used the steps that were mentioned under
https://cwiki.apache.org/confluence/display/VCL/Adding+support+for+partimage+and+partimage-
ng+to+xCAT+2.x+%28unofficial%29
to enable partimage support for xcat. I wasn't sure if I need to change
references to x86 & x86_64 (as directories) to reflect the ppc
architecture, as the web page says "The architecture for the node must
always be set to x86 for this..". I have with me the vmlinuz (kernel
image) and initrd for the capture process. The 2 nodeset commands
nodeset <node> image
nodeset <node> install
fail with the following error msg: "Error: Invalid nodes and/or groups
in noderange: power01".
Also, when I start the capture process using "vcld --setup", again,
there is no option to choose a ppc architecture (I am not sure if I
should be modifying the setup scripts to support ppc architecture). I
continue with the setup process by choosing the architecture as x86_64
(instead of ppc for our Power 7 blade). Operating System is RHEL 5. The
scripts attempts to power down the blade, waits for 120 seconds before
it quits with a failure. The log file is shown at the bottom of the mail.
The script fails saying the blade didn't turn off, but, I can see in my
console that the blade is off and it does not respond to connection
requests. There is a deviation from the configuration that were
mentioned: the blade we are trying to use as a compute node has only 1
ethernet port enabled, hence there is no separate private & public
networks. Will that matter?
Any support with this would be really helpful. Thanks in advance.
Regards,
Sunil Venkatesh

Sunil,
Let's back up a little bit. The first thing to look at is why the image
failed. Unless you created your own stateless image for capturing and
provisioning images, then xCAT will be unable to capture an image from a Power
blade.
Did you use the steps here:
https://cwiki.apache.org/confluence/display/VCL/Adding+support+for+partimage+and+partimage-
ng+to+xCAT+2.x+%28unofficial%29
for modifying xCAT to be able to capture/deploy images? If so, the stateless
images linked to off of that page are for x86 hardware. You will need to
create your own stateless or statelite images for Power blades.

Hi,
We are currently in the process of configuring VCL 2.2.1 to work on a
Power 7 blade. Our current setup is:
1. A web-server that hosts the Database and the Web Code. The same
server acts as the Management node. xCAT is configured as the
provisioning module on this node.
2. Power7 is our compute node.
3. I used the command "vcld --setup" command to create/capture base
image of RHEL 5 that is running on the Power7 blade (by specifying the
IP address of Power7 blade when prompted for an address).
The creation process failed as Xianqing Yu had mentioned to us earlier.
Although, before it failed it created appropriate entries in the tables
image, imagerevision and resource. I was able to "Undelete" the image
from the web page and see it under "New Reservations".
I am facing similar problems that Mike Waldron had faced with the
reservation. Even after making memory adjustment, I wasn't able to make
a reservation. The time table shows all green (available), however, when
I choose any entry from the list, it takes me directly to "New
Reservation" page without any status/feedback. And, I don't see any
reservations created when I check under "Current Reservations". I am
just assuming the groupings of Images and Computers are correct, is
there anyway I could verify the same. Also, if there is any reference to
how the grouping need to be done, please let me know of the same.
Please do correct me if there is anything wrong with the system setup.
